Im quite shocked to see you consider "saving" is horrible design. I don't encourage players or developers alike to base a game mechanic where saving is crucial, but that is another story. If you attacking "saving" in general, then i guess finishing any game would be either impossible or very difficult task to accomplish. Also for "quick saving", sometimes i see it very vital to game and sometimes it is annoyance.
You listed "Difficulty Level" but you didn't give reasons, also for Little Big Planet, and i would like to hear what you have to say about that.
